Dev Server

Launch the local dev environment using the project's dev-runner (packages/scripts/src/dev-runner.ts). The runner handles env symlinks, Docker services, migrations, port allocation, and health checks.

Instructions

1. Resolve application ports (dry run):

   Run the dev-runner in dry-run mode to learn which ports it will use. The runner hashes the worktree/branch name into a port offset so multiple worktrees can run simultaneously.

   bun run dev --dry-run --skip-install --no-browser
   

   If this exits before the runner starts with a missing-package or module-resolution error, run bun ci once and retry the exact same dry-run command. Do not treat other failures as bootstrap errors or retry them this way.

   Parse the numeric offset: and the web: and api: URLs. This offset covers application ports only; do not copy it into --infra-offset without the independent ownership check below.

2. Resolve infrastructure ownership:

   Offset 0 belongs to the root checkout and its shared Docker project. A non-root worktree needs a stable non-zero offset whose Compose project and volumes belong to that worktree.

   Reuse a previously recorded assignment for the same canonical worktree path. For a new assignment, select from the full valid infrastructure range, reserve the candidate with a race-safe lock, and validate all five shifted ports (Postgres, Valkey, RustFS API, RustFS console, and Gotenberg). Reject the candidate if any of those ports intersects the dry-run web or API ports, or if any container or Docker volume already uses the corresponding stella-dev-<offset> project unless its Compose working-directory label matches this worktree. Probe another candidate on any ownership or port collision.

   The runner hashes application offsets into only 400 buckets and checks application ports separately. That hash is not an infrastructure ownership mechanism, and adjacent infrastructure offsets can overlap because RustFS uses consecutive ports.

3. Start the dev runner:

   Launch the full runner in the background. It manages Docker services, env symlinks, db:push, process lifecycle, and readiness polling internally.

   bun run dev --no-browser --infra-offset <resolved-offset>
   

   Run this in the background. The runner exits if any child process dies, so a single background command covers everything. Keep dependency installation enabled on the first run. Add --skip-install only when this worktree is already bootstrapped and its dependencies have not changed.

4. Handle cold-start setup safely:

   The first isolated run creates Docker volumes and applies every migration, so it can take longer. Never reset or repair the shared database to resolve migration drift. In a non-root worktree, confirm the command uses its owned non-zero --infra-offset; in the root checkout, keep offset 0.

   If the runner completes infrastructure and migrations but exits only because its application-readiness deadline elapsed, rerun the same command once. The expensive setup is cached. If the second run fails, inspect its logs and report the blocker.

5. Use the runner's readiness result:

   Capture the live runner output and read the final summary for the exact web and API URLs. Infrastructure startup or another process can make the runner move away from the dry-run application offset, so never poll or report the preliminary URLs from step 1. The runner prints its final summary only after its bounded internal readiness checks pass; do not duplicate those checks or open a browser to verify them again.

6. Report the resolved URLs and status to the user. Leave the runner active until the user asks to stop it.
